To all whom it may concern:

Be it known that I, SHERMAN MCNABB, a citizen of the United States, residing at Prague, in the county of Lincoln and State of Oklahoma, have invented certain new and useful Improvements in Combined Automobile-Jacks and Tire-Pumps; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

y invention is a combined automobile jack and tire pump, provide an extremely simple device which may be used either as-an automobile jack or a tire pump or may be used for performing both duties at the-same time.

Heretofore, it has been common practice to provide tire pumps having means for at tachment to the drive wheels of an automobile and to provide an independent jack whereby the wheel, to which the device is to be attached, may be raised above the ground.

My invention aims to combine the jack and pum above en the invention resides in certain novel features of construction and combination herein described and claimed and shown in the drawings wherein- Figure 1 is a side elevation of a combined pump and jack constructed in accordance with my invention; Fig. 2 is a central vertical section through the device, showing its application to the wheel; Fig. 3 is a horizontal section taken on the line 3-3 of Fig. '2; Figs. 4 and 5 are respectively side and bined ack shank and pump cylinder and the parts carried thereby; Fig. 6 is an inner end view of the hub engaging member; Fig. 7 is a side view thereof; Fig. 8 is a vertical transverse section taken on the line 88 of Fig. 1; Fig. 9 is a face view of the jaw operating ring; Fig. 10 is a view similar to Fig. 6 but showing the clamping jaws in position; Fig. 11 is a vertical transverse section takenen the line 11 1l of Fig. 1; and Fig. 12 is a perspective view of a crank which may be employed for manually operating the device. I

ln the accompanying drawings, 1' have shown an automobile wheel W having the usual hub H which is provided with a nut or dust cap N on its outer end as is common to devices of this character.

The construction so far dwcribed is of inwardly extending and has for its object to in a single article and, to the I hub of an automobile edge views of the com-' common formation and forms no part of the present invention.

Adapted to be positioned on the hub H, as

clearly seen in Fig. 2, is a substantially cylindrical member 1 whose outer end is closed by an upright wall 2 having a polygonal opening 3 at its center, said opening being adapted to receive the nut N. The opposite end of the member 1 is provided with an flange 4: to which an outwardly projecting sleeve 5 is integrally connected, said sleeve being adapted to loosely embrace the inner end of the hub H as clearly seen in the drawings. Formed at suitable intervals in the outer face of the flange 4, is a plurality of radially extending guideways 6 which register with rectangular openings '2' formed through the sleeve 5, said guideways 6 and openings 7 receiving a number of clamping jaws 8 whose inner ends may be serrated, if desired.

In the present embodiment of the invention, the jaws 8 are shown in the form of rectangular rack bars whose teeth 9 are formed adjacent the wheel V, a spiral thread 10 being engaged with said teeth whereby the jaws may he moved inwardly or outwardly when the thread is turned, said thread being here shown as formed integral with a jaw operating ring 11 which is revolubly mounted upon the sleeve 5 and held thereon by means of a nut 12 and a lock nut 12' which are threaded on the outer end of said sleeve. 'lhc'ring 11 is provided with any suitable form of operating handle 13 by which it may be readily turned to move the jaws inwardly into contact with the hub H or outwardly to allow the device to be removed from the hub,

From the above description, it will be seen that I have provided means for clamping the member 1 to the hub H in such a manner as to cause said member to rotate therewith but that this clamping means need not be in the specific form illustrated in the drawings.

Embracing the cylindrical member 1 is a pair of bearing rings ll which are here shown as formed in two sections 1% and 1%", the-latter being formed integral with a pair of arms 15 which rise rigidly from a combined ack of the members ll and l-l areof semi circular formation and are rigidly united by bolts or other suitable fastening means 1 is clearly seen in Figs. 2 and 11, a

shank and pump cylinder '16. is clearly shown in Figs. 5 and ll. both' I preferably provided with upright ribs 21 which contact with the opposite sides of the sleeve 19, thereby retaining the parts in their respective positions at all times. The member 16 is further provided with ratchet teeth 22 which are formed on its opposite sides, said ratchet teeth being engaged by spring pressed pivoted pawls 23 which are mounted on a lever 24, the latter having a portion 25 which surrounds the sleeve 19 and is pivoted thereto as indicated at 26. As clearly shown in Figs. 2 and 3, the pawls 23 project through upright slots 27 which are formed in the opposite sides of the sleeves 19, one of said slots also receiving an outwardly projecting nipple :"28 which is formed on the lower end of the member 16, this feature of construction efiectively preventing said mem-v her from rotating within the sleeve as well as establishing communication between the interior: of the cylinder and a flexible tube 29 which may be provided with any suitable means (not shown) forattachment to the valve stem of a tire.

Mounted for reciprocation in the member 16, is a piston 30, the stem 31 of which rises and is provided with a head 31 located between the arms 15, said head being adapted to be engaged by a suitable cam 32 which is here shown as formed integrally with the member 1, said cam acting to depress the piston 30 against the tension of a coil spring 33 which is interposed between said head and the upper end of the member 16, thus forcing air from the tube 29 on the descent of the piston, the spring 33 acting to return the latter tonormal position. a

"With the parts as above described, the operation of the device is as follows: The member 1 is positioned upon the hub H as shown in Fig. 2 and the ring 11 is rotated by its handle 13 to force the jaws 8 into contact with said hub, thereby securely clamping the member 1 upon the latter. The lever 24 is now rocked around its pivots 26 to cause the pawls 23 to successively engage the ratchet teeth 22 thereby raising the member 16 and consequently the entire wheel W to such an extent as to allow the latter to be positioned out-of contact with the ground. The wheel IV may now be'rotated by the motor of the vehicle, this movemert rotat ng the member 1 and causing the cam 35 to depress the piston 30 at intervals,"between which intervals said piston is returned to normal position by the spring 33.

From the aboveset forth construction, it will be seen that I have produced an extremely simple device which may be used for an automobile jack or for a combined automobile jack and tire pump. The device may further be used as a pump alone by employing a crank 34; which is provided with a polygonal head 35 adapted to be inserted into the opening 3. It will readily be seen that the member 1 may be rotated to reciprocate the piston by the use ofthis crank.

I may here explain that, by the positioning of the ears on the bearing sections 1 1 and 14", said ears may be positioned beneath the axle of a vehicle in which case the device may be used as a jack instead of as a combined pump and jack;

I have described my invention with considerable minuteness and have set forth certain specific embodiments for carrying out the objects of the invention but I wish it understood that-I need not be limited to'the features of construction. herein disclosed oltherwise than as amplified in the appended c aims.
